U.S researchers have established a link between the thick clouds of dust arising from the Sahara desert and the Atlantic hurricanes. They have found that intense hurricanes occurred in the years when dust storms in Sahara were scarce and in the years with stronger dusts storms in Sahara, fewer hurricanes swept across the Atlantic. Jonathan Foley, co-author of this study and the director of the Centre for Sustainability and Global Environment at the University of Wisconsin-Madison, said that the findings of this study are very important, since it established the link between long-term changes in hurricanes with many different factors. The findings of this study could help in better forecasting of the intensity of hurricanes.

 

Scientists believe that the dust clouds from Sahara blown into the Northern Atlantic Ocean by the trade winds, leads to a ‘dimming’ effect that dampens brewing hurricanes, which need heat and moisture to feed them. This study was funded by the US National Oceanic and Atmospheric Administration and its results were published in the journal ‘Geophysical Research Letters’.
